Overview

ICESat Spacecraft

The Submarine Arctic Science Program, SCICEX, is a federal interagency collaboration among the operational Navy, research agencies, and the marine research community to use nuclear-powered submarines for scientific studies of the Arctic Ocean. Unlike surface ships, submarines have the unique ability to operate and take measurements regardless of sea ice cover, weather conditions, and time of year. This allows for a broad and comprehensive investigation of an entire ocean basin. The goal of the program is to acquire comprehensive data about Arctic sea ice, water properties (biological, chemical, and hydrographic), and water depth (bathymetry) to improve our understanding of the Arctic Ocean basin and its role in the Earth's climate system.

SCICEX was officially launched in 1994 after a successful feasibility test in 1993 where civilian scientists joined Navy personnel on a submarine to acquire scientific data. From 1995–1999, five more dedicated science cruises were completed aboard nuclear-powered submarines. Since then, a modified approach has been taken, where some time is set aside for the collection of unclassified scientific data during otherwise classified submarine exercises. These are known as Science Accommodation Missions (SAMs) which are facilitated by the Arctic Submarine Lab (ASL). Guidance on data collection priorities during a SAM is provided in the SCICEX Phase II Science Plan. The most recent SAM took place in November 2012. See a list of all the SCICEX Cruise Dates.

This site is supported by the National Science Foundation (NSF) award number 0632296 for the Arctic Observing Network (AON) and by the Office of Naval Research (ONR) and the U.S. Arctic Research Commission (USARC). SCICEX is a Navy contribution to AON, the observational change component of a federal interagency committee called the Study of Environmental Arctic Change (SEARCH).
